Bushwhacked

The first two Shotgun Westerns starring John “Shotgun” Bishop—part man, part killing machine, and all vengeance.
 
Shotgun
Dr. John Bishop saw his share of death in the Civil War. Then a gang of outlaws invaded his home, slaughtered his family, and cut off his arm. Vowing revenge, Bishop has a gunsmith attach a special shotgun rig where his left arm used to be. Now the man called Shotgun rides deep into the Colorado winter to find and kill the men who murdered everything he once held dear—a journey that will force him to confront the violent legacy of his own outlaw brother—Devlin, a crazy-mean cuss who’d steal the horns off the devil himself.
 
The Bleeding Edge
This time, Dev’s got his cold black heart set on taking over John Chisum’s land, destroying the cattle king’s dream of building a new town and laying down tracks for the railroad. So Chisum hires Shotgun to protect his investment. But when the Bishop family feud turns into an all-out turf war, Shotgun ends up on the wrong side of the law—stuck in the middle between the devil he knows and two deadly new players. Their names are Billy the Kid and Pat Garrett. And this time, there will be blood. . .
